-----------------------------------
Summary: Verify that Streams never creates RocksDB stores unless
they are needed
Key: KAFKA-7367
URL: https://issues.apache.org/jira/browse/KAFKA-7367
Project: Kafka
Issue Type: Improvement
Components: streams
Reporter: John Roesler
We have gotten some reports of Streams creating RocksDB stores unnecessarily
for stateless processes.
We can and should verify this doesn't happen by creating integration tests for
*every* stateless operator that verify that after processing, the state
directory is still empty.
These tests could potentially be backported as far as we care to so that we can
identify and fix potential unnecessary stores in past versions as well.
